Re: [Discuss-gnuradio] Error in hier block with 4 outputs and an async message!
I can reproduce the issue and also confirm your work-around. I pushed a fix to the grcwg repo. See if that works for you guys.

Re: [Discuss-gnuradio] Error in hier block with 4 outputs and an async message!
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Achilleas, you're right, grc omits one of the pad sinks; that is kind of a bug, but I don't know if the terminology really fits; as it seems, gnuradio does not like you to have input and output pads directly connected. I don't know if this is only a precaution to avoid loops, or if there are actual reasons you can't have this in a hier block. However, can you make the error go away by inserting copy blocks where you directly pass through?

Marcus, the error is still there even if you don't have direct connections between in/out pads. See attached Achilleas test_msg_hier.grc Description: Binary data ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] Error in hier block with 4 outputs and an async message!
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Ok, Now I can reproduce your problem. But I do get (in contrast to your error message because of connecting a block to itself): Traceback (most recent call last): File /home/marcus/top_block.py, line 74, in module tb = top_block() File /home/marcus/top_block.py, line 32, in __init__ self.test_msg_hier_0 = test_msg_hier() File /home/marcus/.grc_gnuradio/test_msg_hier.py, line 38, in __init__ self.connect((self.blocks_complex_to_mag_0_0_0, 0), (self, 4)) File /home/marcus/.usrlocal/lib64/python2.7/site-packages/gnuradio/gr/hier_block2.py, line 75, in connect self._connect(points[i-1], points[i]) File /home/marcus/.usrlocal/lib64/python2.7/site-packages/gnuradio/gr/hier_block2.py, line 81, in _connect dst_block.to_basic_block(), dst_port) File /home/marcus/.usrlocal/lib64/python2.7/site-packages/gnuradio/gr/runtime_swig.py, line 2890, in primitive_connect return _runtime_swig.hier_block2_sptr_primitive_connect(self, *args) ValueError: destination port 4 out of range for test_msg_hier(1) Which fits quite well into your observation that there is a lack of order in the output. As it seems, the output signature of your hier block is 4 streams, which is correct. So I guess GRC is getting the hiccups because the message stream is not the last pad; I think they're ordered alphabetically. Can you give the block an id like __verylast? does that help?
